Stephen Stair has posted this update:

I've mainly been reworking some sections of code to better support IP fragmentation, I should be able to support that soon. And, the test program is coming along... version 0.1 can be found on Stephens page. - Version 0.1 only includes a "wardriving" app, capable of cataloging up to 512 access points the DS detects. More will be added before too long. I've been wasting a good deal of time lately - however, I'm getting back on track now and hopefully can manage to work on this a good deal more in the near future. Expect good things
